small-felt-area earthquake

Based on the first arrival P and S data of 4 625 regional earthquakes recorded at 174 stations dispersed in the Yunnan and Sichuan Provinces, the 3-D velocity structure of crust and upper mantle in the region is determined, incorporating with previous deep geophysical data.

根据云南和四川地震台网 1 74个台站记录的 4 62 5个区域地震初至 P波和 S波走时资料 ,并结合其它深部地球物理资料 ,确定了川滇地区地壳上地幔三维速度结构 。

The shallow seismic prospecting is one of indispensable important prospecting method to civic seismic microzoning.

浅层地震勘探是城市地震小区划中不可缺少的重要勘探手段之一。
